[FGZstar] If you're only using it for toast then freeze what you dont use - already sliced. Most toasters will toast it ok from frozen. When working away from home I make bread on Friday or Saturday and then slice whatever's left after the weekend and freeze it for Mrs INJ to use, a slice at a time, during the week.
You can toast from frozen in less time than it takes to grill bacon - but it would take a little longer to just thaw the bread, unless you use a microwave.
Freeze a loaf in pairs of slices? Then you can hammer them (in pairs) into the toaster slot and put it on the 'barely stiffened up' setting to *just* thaw it to the perfect state for wrapping around your bacon sandwich.
I freeze thinly sliced granary loaves from a good local baker, and I generally find I can 'peel off' individual slices whenever I need to, although I do sometimes need to use a knife to split them apart. Individual slices defrost in around 20-30 minutes if you just separate them and lay them out on a plate, and 30 seconds in a toaster does the trick too. The key part of my technique is using thin-sliced brown bread which lets me split slices off while the loaf is still frozen solid - but if you can find bread like that it does save the faff of splitting it into sections before freezing.
